SPECIFICATION forming para of Letters Patent No. 705,319, dated July 22,1902. Application led October 12, 1899. Renewed May 17, 1902. Serial No. 107.826. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM T. BUSH, a citizen ofthe United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Water-Closet Bowls; and I declare the following to be a full, clear, and exact vdescription of the invention, such-as will enable others skilled in the art to which itpertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specilication.

This invention relates to water-closet bowls, and has for its object an improved bowl in which water introduced into the bowl through a tubular rini that surrounds the upper part of the bowl is directed downward obliquely rather than straight, and the motion of the Water resulting from the shape of the bowl, the motion of the Water in the tubular rim, and the oblique discharge-outlet from said rim cause the water toV iiow downward along a spiral path and the water is carried around and down, so that it Washes the inner surface of the bowl completely.

In the drawings, Figure l is a horizontal section through the top ot' the bowl, the section being through the horizontal tubular water-passage that surrounds the upperv rim. Fig. 2 is a vertical section taken on the curved line A A A A of Fig. 1.

The bowl may be of any well-known and approved forms of bowls in use 4having a curvilinear cross-section, the improvement being applicable to either the ordinary trapbowl or to the Siphon-jet style of bowl. I

Around the upper rim of the bowl isa passage C, that leads from the water-inlet D, curves around the top of the bowl, and terminates at the back of the bowl at a. Through the bottom of the tubular passage C are a number of perforations, all ot' which are oblique to the passage C. VSome of these perforations b are substantially round holes and others, d, e, and f, are oblong holes of large capacity. The oblong holes of large capacity are arranged with reference to the shape of the inner walls of the bowl below the tubular passage and arranged to deliver water in larger quantities at certain places on the inner surface of the bowl than at other places. The large hole d will deliver a larger body of .mates to a spiral.

water upon one side and toward the rear part A of the bowl, and the large hole e will delivera large stream of water upon the side toward the front part of the bowl, and these two portions of the surface are the parts where the larger quantities of Water are most required.

The large hole f is placed at the end of the passage-way C asa clean-out hole for the passage itself to prevent the accumulation of sedimentary deposit in the passage.

The inner surface of the bowl approaches more nearly to the form of an inverted cone than any other geometrical ligure; but its surface is so warped thatA no strict designating term can be applied to it, and the path of the water running obliquely downward around the surface is not a true spiral, but approxi- The water traveling in a spiral traverses a longer path than when it travels directly downward and is pressed against the side of the bowl by the centrifugal force due to the component of its velocity, which is tangential to the horizontal section of the curved walls of the bowl, and consequently greater'efficiency is obtained from a given quantity of water. The water entering the tubular rim at one point and all owing in one direction has a considerable velocity in a direction tangential to the horizontal section of the curved walls of the bowl at every point of said rim, and a portion ot' said tangential velocity remains as a component of the velocity of the water passing downward in the' bowl. The various streams of water inl the bowl having tangential velocities in the'same direction do not interfere with and impede each other, but unite to form a mass of whirling water in the bowl.

l. A Water-closet bowl havinga channeled liushing-rimequipped with large ports near the fluid-entrance to said rim for discharging cleansing fluid upon the rear wall of the bowl, smaller ports located at intervals around said rim, partition at the end'of the channel in the rim and a large port adjacent to said partition.

Iony

small ports around the circumference of said rim; and a partition dividing the inlet and discharge ends of said rim.

3. A water-closet bowl consisting of a hopper-shaped receptacle having a flushing-rim at its top, said rim being provided with a series of large ports or openings located near the inlet end of said rim for discharging a large quantity of water upon the rear wall ot the bowl; a large port or opening located adjacent to the partition dividing the inlet and delivery portions ot said rim and through which water passes to cleanse said partition; and a series of small ports or openings intermediate the large ports, or openings.

4. In combination, with a flushing-tank, a water-closet bowl having a rim provided with a circular channel or passage equipped with ports on its lower side; apartition located between the inlet and final discharge openings on said rim; and a series of large ports and small ports disposed substantially as set forth throughout said rim.

5. The herein-described water-closet bowl, having a rim or channel divided by a partition as set forth, said rim or channel being provided with a series of large ports having inclined walls; two series of small ports also having inclined walls; an intermediate large port or opening with inclined Walls; and a large port with inclined Walls located adjacent to the partition dividing the inlet and discharge ends of said channel.

In testimony whereof I sign this specifica tion in the presence of two witnesses.
